To'tzZZ whom it may concern:

. Be it known that I, LEMUEL P. COULTER, a citizen of the United States, residing at Huntington Park. in the county of Los Angeles and State of California, have invented new and useful Improvements in Gas Burners, of which the following is a specification. Y

This invention relates to improvements in liquid fuelburners.

The principal object of this invention is to produce a burner which will use a liquid fuel, vaporize the same and then burn as a gas without giving off a carbon deposit.

Another object of this invention is to produce a burner of this type which is simple in construction, free from complicated parts and consequently. easy to operate, and economical to manufacture.

A further object of this invention is to produce a burner which may be used in any ordinary cook-stove or the like thereby doing away with the usual coal'or wood fuel.

Other objects and advantages will be apparent during the course of the following description. 7

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a cross-section of a cool. stove fire-box having my invention attached thereto,

Fig. 2 is a side elevation of my burner,

Fig.3 is a top plan view of my burner,

Fig. 4: is a cross-section taken on theline 44 of Fig. 5, x

Fig. 5 is a cross-section taken on the line 5-5 of Fig. 4:, and

Fig. 6 is a cross-section taken on they line 66 of Fig. 4. I I p In the drawings wherein forthe purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a fire-boxof the ordinary cook-stove having the usual grate 6, while the numeral 7 designates a liquid fuel tank having an outlet pipe 8 attached to the "bottom thereof. This plpe is of an extremely small diameter and is known to trade as hollow wire. At 9 I have shown a pipe entering the top of the tank which pipe is adapted to be connected to an air pressure pump for the purpose of. placing air pressure on the of the-liquid fuel. On the pipe 8 Iplapea shut-off valve 11 and preferably-place. the

.same' some distance away from the stove; This pipe 8 is carried through the sidewall of the stove and connects through the medium of a'union 12 to a retort pipe 1'3 supported above and resting on the burner as a whole, this pipe 13 after passing across the; top of the burner extends downwardly as shown at 14 and enters a T connectionwithin which is a needle valve controlled through the medium of a rod 17 having a handle 18 thereon. A nozzle 19 projects from the T 16 into the end wall of a casting 21, which casting i provided with a bottom 22 having an opening 23 at one end thereof.

This

opening enters a chamber 24 formed by an arched portion 26 integral with the casting 21. The arched portion 26 referred toterminates in an upwardly extending port or outlet 27 directly above which is a curved baffle 28 suspended fromthe under side of a 1 trough 31 and extending across the entire length of the casting 21 and being disposed directly beneath the retort pipe 13. ,At 32 and 33 I have shown burner plates slantingly disposed and supported upon the casting 21. These burner plates are provided with v sawed slots' for the passage of gas there through and are prevented from warping by tie pieces 34 and 36. At 37 I have shown a tray disposed beneath the T connection 16 having the needle valve therein.

The operation of my The tank 7 is filled with a liquid fuel such as coal-oil and air pressure isplaced'on top device is as follows through the, medium of the pipe 7. A little 3 oil is now placed into the trough 31 and the tray 37 and ignited, whichheats the retort pipe 13 and the T connection 16. I now open the valve 11 and allow the liquid fuel to enter the retort 13 where it is immediately vaporized and passes to a needle valve located in the T connection 16. By now r0- tating the handle 18. the needle valve is opened and allows the atomized fuel to enter the chamber 2a. This produces an injector action which draws in'a large amount of air through the opening 23 which mixes with this vaporized fuel. This mixture exhausts upwardly through the chimney 27 strikingthe baffle plate 28 thus filling the a burner which Willhave long life and one v Which does not become clogged through scale formed by oxidation through contact With the fuel or the hot metall' I 7 It is to be understood that the form of my invention herewith shovviri and described is to be taken Jas'a preferred example 'of the same andthat variouschanges in the shape, sizeand arrangement of parts may be re: sorted to Without departing from the spirit of the invention or the scope of the subjoined claim. l

Having thus described my invention, I

claim In a burner the combination With a casting having an orifice formed therein, of a chamber formed above said orifice, having'an outlet therein, a baffle plate mounted above the outlet of said chamber, burner plates movably secured On said casting and having a series of parallel slots formed therein, a trough formed above and between said bi'1rner'plates,a retort pipe supported above said trough, means for controlling the flow of fuel from said retortpipeto saidfchjaniberQand means preheating'saidcontrol means.
